Spreadsheet cells can contain raw data (numbers, dates, text labels, images, web addresses and so on) or formulae. In this spreadsheet, the value in column D (Current Value) is the result of a formula: multiplying Current Shareholding by Current Share Price. The selected cell (D5) thus contains the formula =(B5*C5) which you can see displayed in the Data Entry box; while the result of the calculation is displayed in the cell D5 itself.
